2(a). The table below shows the incomes and rates of income tax levied on four professionals in an economy (Director: income $8,000, tax rate 10%; Engineer: income $7,000, tax rate 12%; Civil Servant: income $5,000, tax rate 18%; Nurse: income $6,000, tax rate 15%). Calculate the disposable incomes of the four individuals.

Model answer

Disposable income = Income − Tax. Director: Tax=10%×8000=$800; Disposable income = 8000−800 = $7,200. Engineer: Tax=12%×7000=$840; Disposable income = 7000−840 = $6,160. Civil Servant: Tax=18%×5000=$900; Disposable income = 5000−900 = $4,100. Nurse: Tax=15%×6000=$900; Disposable income = 6000−900 = $5,100.
